To all whom t may concern.'

Be it known that I, GEORGE W.TH0MP soN, a citizen of the United States, residing at Springfield, Greene county, Missouri, have invented a new and useful Acetylene- Gas Generator, of which the following is a specification.

This invention relates to acetylene gas generators.

An object of the invention is to provide an acetylene gas generator comprising two receptacles, each of which is arranged to contain a gas forming material which when brought together generate the gas, in combination with a passage through which the gas forming material may pass from one of said receptacles into the other, and mechanism` for controlling said passage to deliver measured lquantities of the gas forming material from one of said receptacles to the other to generate gas when thegas generated in the second receptacle becomes depleted or reduced to or below a desired minimum.

Another object of the invention is to provide an apparatus for generating gascomprising a generating tank arranged to contain one of the gas forming materials and a receptacle arranged to contain another gas forming material, in combination with a device for controlling the delivery of the gas forming material from the receptacle into the generating tank, and means forl controlling the operation of said device in conformity with the variation of the quantity and pressure of the gas generated in the generating tank.

With the foregoing and other objects in view, I have illustrated my invention in the accompanying drawings, in which- Figure 1 is a view. illustrating in section the mechanism for delivering the gas form- I ing material from the receptacle into the generating tank.

Fig. 2 is a sectional view on the hne 2 2 of Fig. 1.

Fig. 3 is a sectional view on the lme 3-3 of Flg. 1. V

The generating tank 1 1s arranged to contain one of the gas forming materials, such as water, and is provided with an opening through which the material may be delivered into the tank, saidpopening being normally closed by a removable plug or closure 2. The bottom of the tank 1 is provided with a depending portion 3 having a removable closure 4 which may be detached in order to permit cleaning of the tank 1 and the removal therefrom of any deposits or settlings.

The receptacle 5, is supported above the tank 1 and is arranged to contain the other gas forming material, such as carbid. The receptacle 5 is provided with a hoppershaped bottom 6 having a depending open passage .7 extending into the tank l. The inclined walls of the bottom cause the carbid to move toward the passage 7 from which thecarbid may be delivered into the generating tank. The receptacle 5 is provided With an opening having a removable closure 8 through which the material may be placed into the receptacle.

A vertical shaft 9 is supported by an appropriate frame 10, or otherwise as desired and has a plate 11 secured to the lower end thereof for supporting the carbid. A shell 12 is mounted in the passage 7 and is movable toward and away from the plate l1. Thus when the shell 12 is in contact with the plate 11 the passage is closed and none of the carbid can pass from the receptacle into the generating tank; and when the she-ll 12 is raised, as illustrated in Fig. 1, the carbid may pass between the shell and the plate 11 and drop into the. liquid gas formin material in the generating tank. This evice and the means for operating it constitute the subject-matter of the present'invention.

As illustrated the shell 12 is supported by a series of rods 13 having their upper ends connected to a supporting member` 14 which is supported by a sleeve 15 enclrcling the shaft 9 and extending through a frame secured to the upper wall of the receptacle 5. The shaft 9 is revoluble within the sleeve 15.

A lever 16 is pivoted to a support 17 and is connected by pin-in-slot connection 18k with the sleeve 15 so that by operation of the lever 16 the sleeve 15 may be ralsed and lowered as required to move the shell 12 to and from closed position. Normally the lever 16 is supported in raised position by a spring 19 so that the shell 12 is norphragm-23 within the case 21. A pipe 24 operating the lever 16 causing said lever to' constitutes a passage for conducting gas from the tank 1 into the case 21 below the diaphragm 23 so that when the quantity .and pressure -of the gas within the tank '1 rises to the desired point the diaphragm 23 will be aii'ected thus raising the link 20 and actuate the shell 12 to closed position in contact with the plate 11. When the yquantity and pressure of the gas in the generating tank becomes reduced the shell 12 is moved to open position automatically by the spring 19 acting again^st the lever 16. In this way the passage for delivering the carbid from the receptacle 5 into the generatingtank is automatically opened and closeid in harmony with the variation in the quantity-and pressure ofthe gas in the generating tank.

In order to assure discharge of the carbid lfrom the plate 11 movement of said plate is desirable. In the embodiment illustrated the movement of the plate 11 is a rotary movement imparted by the operation of an 'electric motor 25 driving a chain 26 engaging a sprocket wheel 27, secured to thel upper portion of the shaft 9. Thus when the motor 25 is operatin the shaft 9 is constantly rotated. Provlsion is made for stopping rotation of the shaft 9 concurrently with the movement ofthe shell 12 toclosed position unless it is not desired that the plate 11 rotate when the passage from the receptacle 5 to the generating tank is closed. One of th'e wires in the circuit for operating the motor is connected with a contact member 28 and the other wire of the circuit is connected to the end of the lever 16. When the leverf16 is in its raised'position in which it supports the shell 12 in open position, said lever is in contact with'the contact member 28 and the circuit is closed, thus causin the motor to operate and rotate the sha 9. NV hen the lever 16is operated as required to move the shell 12 lto closed position the lever 16 is moved out of contact with the contact member 28 thus opening the circuit through f which the motor 25 is energized. As a result of this o ration the motor'stops and tion to prevent elivery of the carbid into the shaft 9 aso stops rotating so that the plate 11 is no longer turned. This occurs )ust prior to the time that the shell 12 contacts with the plate 11, so that there is no interference by the parts with each other.

On some occasions 4it :may be desired to hold the shell 12 ermanently in closed posithe generating tank `and the consequent generation of gas. Various expedients may be employed for this purpose and, in the embodiment shown, the spring 19 encircles a rod 29 which extends through an arm 30 on the lever 16. The upper end of the rod 29 -is threaded and is, equipped with a manipulative nut 31 by operation of which the lever 16 may be lowered out of contact with Y the contact member 28 to retain the shell 12 in engagement with the plate 11. When the nut 31 is setin the adjustment mentioned it will permanently retain the shell 12 in closed position until the nut is released or adjusted in position to permit the spring 19 to raise the lever 16 and open the passage into the generating tank. Y,
